Device for driving a vehicle and in particular a railway vehicle

摘要

An electric motor is placed around the axle of a vehicle but includes a rotor that does not contact the axle. A drive element is fastened to the axle and extends radially from the axle. The drive element for driving the axle is coaxially fastened to the axle but located laterally with respect to the electric motor. The rotor includes a disk that directly engages elements in a peripheral region of a drive element disk, the engagement occurring at a point remote from the axis of the axle.
